[Graphic Omitted] UBS Global Asset Management Insured Municipal Income Fund Inc. Semiannual Report September 30, 2002 Insured Municipal Income Fund Inc. November 14, 2002 DEAR SHAREHOLDER, We present you with the semiannual report for Insured Municipal Income Fund Inc. for the six months ended September 30, 2002. AN INTERVIEW WITH PORTFOLIO MANAGER WILLIAM VERONDA Q: HOW DID THE FUND PERFORM DURING THE PERIOD RELATIVE TO ITS PEERS? A: For the six months ended September 30, 2002, the Fund's net asset value advanced 8.21% and its market price increased 11.36%, underperforming its competitors as measured by the Lipper Insured Municipal Debt Funds (Leveraged) Median. The Lipper Median's net asset value and market price grew 11.01% and 12.20%, respectively. The Fund's shorter average duration compared to its peers was the primary contributor to its performance versus the benchmark. (For more performance information, please refer to "Performance At A Glance" on page 4.) Q: COULD YOU DESCRIBE THE ECONOMIC ENVIRONMENT DURING THE PERIOD? A: As the reporting period began, there were increasing signs that a sustained economic rebound was taking place. This prompted the Federal Reserve Board (the "Fed") to shift from an easing stance (to combat economic weakness) to a neutral stance. The change in policy appeared warranted, as gross domestic product (GDP) accelerated to a 5.0% growth rate during the first quarter of 2002. However, the uptick proved short-lived. Ongoing threats of terrorism, turmoil in the Middle East, anemic corporate spending, waning consumer confidence in light of the stock market's decline, and corporate accounting scandals all took their toll. The end result--second quarter 2002 GDP growth was a less-than-expected 1.3%. Although the third quarter figure came in at 4.0%, as of this writing, investors were already focusing on fourth quarter GDP, since it may be an indicator as to whether a sustainable economic recovery is likely. Q: HOW DID THE BOND MARKET PERFORM DURING THE SIX MONTH PERIOD? A: Given the uncertainties regarding the economy, the weak stock market, and geopolitical concerns, the bond market rallied sharply during the period. Investors ------------------------- INSURED MUNICIPAL INCOME FUND INC. INVESTMENT GOAL: High level of current income exempt from federal income tax, consistent with preservation of capital. PORTFOLIO MANAGER: William Veronda, UBS Global Asset Management (US) Inc. COMMENCEMENT: June 8, 1993 NYSE SYMBOL: PIF DIVIDEND PAYMENTS: Monthly ------------------------- -------------------------------------------------------------------------------- UBS Global Asset Management 1 Insured Municipal Income Fund Inc. were drawn to the relative safety and strong performance offered by fixed income securities in general, and the municipal market participated in this upswing. Q: WHILE THE FUND GENERATED STRONG ABSOLUTE RETURNS, IT LAGGED ITS BENCHMARK DURING THE PERIOD. WHAT WERE SOME OF THE FACTORS THAT LED TO THE FUND'S RELATIVE UNDERPERFORMANCE? A: To some extent, our goal of limiting the Fund's capital gains adversely affected its results during the period. Based on the municipal market's strong performance in recent years, nearly every security in the portfolio has risen in price. To avoid locking in capital gains, we've tended to hold on to our positions. Consequently, some of the bonds in the Fund's portfolio have "aged" to the point where they have short maturities. With a shorter duration than the benchmark, the Fund underperformed its peers in the falling interest rate environment. Q: HOW ARE YOU CURRENTLY POSITIONING THE FUND'S PORTFOLIO? A: We are continuing to selectively focus on bonds that have longer durations, typically those with maturities that more accurately reflect the municipal market as a whole. This positioning has increased the Fund's flexibility to purchase what we believe are attractively structured and priced municipal securities. In particular, we're focusing on bonds with maturities in the 15- to 20-year range, as we believe these issues offer a "sweet spot" in terms of their risk/reward characteristics: while we give up a little bit of yield versus 30-year issues, 15- to 20-year bonds are less volatile than their longer-term counterparts. Q: TO ILLUSTRATE YOUR INVESTMENT STRATEGY, PLEASE DESCRIBE SOME HOLDINGS THAT YOU PURCHASED DURING THIS REPORTING PERIOD? A: Our purchase of Chicago, Illinois insured bonds--Chicago Project-Ser. A--which mature in 2042 and offer a 5% coupon, is one result of our focus on longer duration securities. The timing of our purchase proved advantageous, as these securities have already appreciated roughly 9% in value compared to their issuance price (as of period end). Post period-end, we purchased Georgia Municipal Electric Authority bonds. We purchased a large block of these quality securities at an attractive price. These bonds mature in 2018 and provide a 5% coupon. Q: WERE THERE ANY SECTORS OF THE MARKET THAT YOU PLACED MORE EMPHASIS ON DURING THE PERIOD? A: The Fund's portfolio tends to be highly diversified. When an overweight of a particular sector occurs, it is due to the fact that we view it as being highly attractive. -------------------------------------------------------------------------------- 2 UBS Global Asset Management Insured Municipal Income Fund Inc. Q: LASTLY, WHAT IS YOUR SHORT-TERM AND LONG-TERM OUTLOOK FOR THE MARKET? A: We believe a modest economic expansion will take hold and that a double-dip recession--while possible--is unlikely. Given a subdued growth rate, we feel that interest rates will remain in a trading range--a change from the falling rate environment we've seen over the past few years. As such, we anticipate continuing our strategy of emphasizing longer-term securities at attractive points on the yield curve. We will also continue to stress credit quality in the portfolio to avoid any "contagion" from weakness in the corporate bond markets. Our ultimate objective in managing your investments is to help you successfully meet your financial goals. We thank you for your continued support and welcome any comments or questions you may have.

Notes to Financial Statements (unaudited) ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Insured Municipal Income Fund Inc. (the "Fund") was incorporated in Maryland on February 18, 1993, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended, as a closed-end diversified management investment company. The Fund's investment objective is to achieve a high level of current income that is exempt from federal income tax, consistent with the preservation of capital. The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires Fund management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies: VALUATION OF INVESTMENTS--The Fund calculates its net asset value based on the current market value, where available, for its portfolio securities. The Fund normally obtains market values for its securities from independent pricing sources and broker-dealers. Independent pricing sources may use reported last sale prices, current market quotations or valuations from computerized "matrix" systems that derive values based on comparable securities. If a market value is not available from an independent pricing source for a particular security, that security is valued at fair value as determined in good faith by or under the direction of the Fund's Board of Directors (the "Board"). The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with sixty days or less remaining to maturity, unless the Board determines that this does not represent fair value. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--Investment transactions are recorded on the trade date. Realized gains and losses from investment transactions are calculated using the identified cost method. Interest income is recorded on an accrual basis. Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments. DIVIDENDS AND DISTRIBUTIONS--The Fund intends to pay monthly dividends to common shareholders at a level rate that over time will result in the distribution of all of the Fund's net investment income remaining after the payment of dividends on any outstanding preferred shares. The dividend rate on the common stock is adjusted as necessary to reflect the performance of the Fund. Dividends and distributions to common shareholders are recorded on the ex-dividend date. Dividends to preferred shareholders are accrued daily. The amount of dividends from net investment income and distributions from net realized capital gains is determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capi- -------------------------------------------------------------------------------- UBS Global Asset Management 19 Insured Municipal Income Fund Inc. Notes to Financial Statements (unaudited) tal accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. CONCENTRATION OF RISK The Fund follows an investment policy of investing primarily in municipal obligations of various states. Economic changes affecting those states and certain of their public bodies and municipalities may affect the ability of the issuers within those states to pay interest on, or repay principal of, municipal obligations held by the Fund. INVESTMENT ADVISOR AND ADMINISTRATOR The Board has approved an investment advisory and administration contract ("Advisory Contract") with UBS Global Asset Management (US) Inc. ("UBS Global AM") under which UBS Global AM serves as investment advisor and administrator of the Fund. UBS Global AM is an indirect wholly owned asset management subsidiary of UBS AG, an internationally diversified organization with headquarters in Zurich, Switzerland and operations in many areas of the financial services industry. In accordance with the Advisory Contract, the Fund pays UBS Global AM an investment advisory and administration fee, which is accrued weekly and paid monthly, at the annual rate of 0.90% of the Fund's average weekly net assets. For the six months ended September 30, 2002, UBS Global AM voluntarily waived $294,897 in investment advisory and administration fees from the Fund. COMMON STOCK There are 199,997,000 shares of $0.001 par value common stock authorized and 20,628,363 common shares outstanding at September 30, 2002. AUCTION PREFERRED SHARES The Fund has issued 800 shares of Auction Preferred Shares Series A, 800 shares of Auction Preferred Shares Series B, 800 shares of Auction Preferred Shares Series C and 600 shares of Auction Preferred Shares Series D, which are referred to herein collectively as the "APS." All shares of each series of APS have a liquidation preference of $50,000 per share plus an amount equal to accumulated but unpaid dividends upon liquidation. Dividends, which are cumulative, are generally reset every 7 days for APS Series A, 28 days for APS Series B, 90 days for APS Series C and 7 days for APS Series D. Dividend rates ranged from 1.249% to 1.650% for the six months ended Septem- ber 30, 2002. The Fund is subject to certain restrictions relating to the APS. Failure to comply with these restrictions could preclude the Fund from declaring any distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of APS at liquidation value. -------------------------------------------------------------------------------- 20 UBS Global Asset Management Insured Municipal Income Fund Inc. Notes to Financial Statements (unaudited) The APS are entitled to one vote per share and, unless otherwise required by law, will vote with holders of common stock as a single class, except that the preferred shares will vote separately as a class on certain matters, as required by law. The holders of the preferred shares have the right to elect two directors of the Fund. FEDERAL TAX STATUS For federal income tax purposes, the components of net unrealized appreciation of investments at September 30, 2002 were as follows: Gross appreciation (investments having an excess value over cost).. $35,233,399 Gross depreciation (investments having an excess of cost over value) ..................................................... (67,649) ----------- Net unrealized appreciation of investments ........................ $35,165,750 =========== At September 30, 2002, the components of accumulated earnings on a tax basis were substantially the same as for financial reporting purposes. The tax character of distributions paid to shareholders during the period ended September 30, 2002 and the fiscal year ended March 31, 2002, was tax-exempt income. For the six months ended September 30, 2002, total aggregate purchases and sales of portfolio securities, excluding short-term securities, were $27,430,016 and $19,978,636, respectively. The Fund intends to distribute substantially all of its tax-exempt income and any taxable income and to comply with the other requirements of the Internal Revenue Code applicable to regulated investment companies. Accordingly, no provision for federal income taxes is required. In addition, by distributing during each calendar year substantially all of its net investment income, net realized capital gains and certain other amounts, if any, the Fund intends not to be subject to a federal excise tax.

GENERAL INFORMATION (UNAUDITED) THE FUND Insured Municipal Income Fund Inc. (the "Fund") is a diversified, closed-end management investment company whose shares trade on the New YorkStock Exchange ("NYSE").The Fund's investment objective is to achieve a high level of current income that is exempt from federal income tax, consistent with the preservation of capital. The Fund's investment advisor and administrator is UBS Global Asset Management (US) Inc. ("UBS Global AM"), an indirect wholly owned asset management subsidiary of UBS AG, which has over $71.4 billion in assets under management as of October 31, 2002. Effective May 20, 2002, William Veronda assumed primary responsibility for the day-to-day management of the Fund. Mr. Veronda is an Executive Director and portfolio manager of UBS Global AM. Mr. Veronda joined UBS Global AM in September 1995 and has led its municipal research group since that date. Mr. Veronda previously served as the portfolio manager for PaineWebber Municipal High Income Fund from September 1995 until March 2001. INVESTMENT POLICY CHANGES The Fund's Board approved modifications to the Fund's investment policies as a result of a new rule promulgated by the Securities and Exchange Commission. This rule generally requires a fund with a name suggesting that it focuses on a particular type of investment to invest at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in the type of investment suggested by its name. The investment policy changes became effective on April 8, 2002. These changes are not expected to affect materially portfolio management. The new 80% policy has been adopted as a "fundamental" investment policy; the Fund may not deviate from this 80% policy without shareholder approval. Many of the Fund's other investment policies are non-fundamental policies and may be changed by its board without shareholder approval. The Fund will interpret these new policies as if the following phrase appeared immediately after the words "net assets": "(plus the amount of any borrowing for investment purposes)." If subsequent to an investment, the Fund's 80% policy is no longer met (e.g., bonds are called resulting in a large influx of cash), then under normal circumstances, the Fund's future investments would be made in a manner that would bring the Fund's investments back in line with the 80% threshold. In order to place these changes in context, reproduced below are prior policies that were impacted by this change as well as new policies which replace the prior policies: -------------------------------------------------------------------------------- UBS Global Asset Management 23 Insured Municipal Income Fund Inc. GENERAL INFORMATION (UNAUDITED) INVESTMENT POLICY CHANGES (CONTINUED) PRIOR POLICIES IMPACTED BY CHANGE: The Fund normally invests substantially all of its assets in a diversified portfolio of long-term Municipal Obligations that are insured as to the timely payment of both principal and interest by an entity that, at the time of investment, has a claims-paying ability rated Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO or (with respect to 20% of the Fund's total assets) that are, at the time of investment (1) backed by an escrow or trust account containing sufficient U.S. government or U.S. government agency securities to ensure the timely payment of principal and interest; (2) guaranteed as to timely payment of principal and interest by an entity which has a credit rating of Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO; or (3) not insured, guaranteed or backed by escrows but rated Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO. All the Municipal Obligations described above will have, at the time of investment, ratings of Aaa from Moody's, AAA from S&P or equivalent ratings from another NRSRO or (with respect to the Municipal Obligations described in (1) above), if unrated, will have been determined by the investment advisor to be of comparable quality to Municipal Obligations that have received such ratings. In addition, the Fund under normal circumstances invests at least 65% of its total assets in income producing securities. "Long-term" means Municipal Obligations with maturities in excess of 10 years. The Fund normally invests substantially all of its assets in long-term Municipal Obligations. However, in order to invest cash reserves or when, in the opinion of the investment advisor, no suitable long-term Municipal Obligations are available, the Fund may invest up to 20% of its total assets in high quality short-term Municipal Obligations that are rated, at the time of investment, no lower than MIG-2 by Moody's, SP-2 by S&P or the equivalent by another NRSRO or, if unrated, that are determined by the investment advisor to be of comparable quality to Municipal Obligations that are rated at least MIG-2 or SP-2. These short-term Municipal Obligations may include variable or floating rate demand notes and similar instruments that trade as short-term obligations. For temporary defensive purposes, the Fund may invest without limit in such short-term Municipal Obligations. In addition, if in the opinion of the investment advisor no suitable short-term Municipal Obligations are available, the Fund temporarily may hold cash and, with respect to up to 20% of its total assets, invest in taxable money market instruments. -------------------------------------------------------------------------------- 24 UBS Global Asset Management Insured Municipal Income Fund Inc. GENERAL INFORMATION (UNAUDITED) INVESTMENT POLICY CHANGES (CONTINUED) REVISED POLICIES: The Fund normally invests substantially all of its assets in a diversified portfolio of long-term Municipal Obligations. Under normal circumstances, the Fund invests at least 80% of its net assets in insured Municipal Obligations, the income from which is exempt from regular federal income tax. "Insured Municipal Obligations" are Municipal Obligations that are insured as to the timely payment of both principal and interest by an entity that, at the time of investment, has a claims-paying ability rated Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO. The Fund may invest up to 20% of its net assets in Municipal Obligations that are not insured but that are, at the time of investment, (1) backed by an escrow or trust account containing sufficient U.S. government or U.S. government agency securities to ensure the timely payment of principal and interest; (2) guaranteed as to timely payment of principal and interest by an entity which has a credit rating of Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO; or (3) not insured, guaranteed or backed by escrows but rated Aaa by Moody's, AAA by S&P or an equivalent rating by another NRSRO. All the Municipal Obligations described above will have, at the time of investment, ratings of Aaa from Moody's, AAA from S&P or equivalent ratings from another NRSRO or (with respect to the Municipal Obligations described in (1) above), if unrated, will have been determined by the investment advisor to be of comparable quality to Municipal Obligations that have received such ratings. "Long-term" means Municipal Obligations with maturities in excess of 10 years at the time of purchase. The Fund normally invests substantially all of its assets in long-term Municipal Obligations. However, in order to invest cash reserves or when, in the opinion of the investment advisor, no suitable long-term Municipal Obligations are available, the Fund may invest up to 20% of its net assets in high quality short-term Municipal Obligations that are rated, at the time of investment, no lower than MIG-2 by Moody's, SP-2 by S&P or the equivalent by another NRSRO or, if unrated, that are determined by the investment advisor to be of comparable quality to Municipal Obligations that are rated at least MIG-2 or SP-2. These short-term Municipal Obligations may include variable or floating rate demand notes and similar instruments that trade as short-term obligations.

In addition, if in the opinion of the investment advisor no suitable short-term Municipal Obligations are available, the Fund temporarily -------------------------------------------------------------------------------- UBS Global Asset Management 25 Insured Municipal Income Fund Inc.

GENERAL INFORMATION (UNAUDITED) DIVIDEND REINVESTMENT PLAN The Fund's Board has established a Dividend Reinvestment Plan (the "Plan") under which all common shareholders whose shares are registered in their own names, or in the name of UBS PaineWebber Inc. or its nominee, will have all dividends and other distributions on their shares of common stock automatically reinvested in additional shares of common stock, unless such common shareholders elect to receive cash.Common shareholders who elect to hold their shares in the name of another broker or nominee should contact such broker or nominee to determine whether, or how, they may participate in the Plan.The ability of such shareholders to participate in the Plan may change if their shares are transferred into the name of another broker or nominee. A common shareholder may elect not to participate in the Plan or may terminate participation in the Plan at any time without penalty, and common shareholders who have previously terminated participation in the Plan may rejoin it at any time. Changes in elections must be made in writing to the Fund's transfer agent and should include the shareholder's name and address as they appear on the share certificate or in the transfer agent's records. An election to terminate participation in the Plan, until such election is changed, will be deemed an election by a common shareholder to take all subsequent distributions in cash. An election will be effective only for distributions declared and having a record date at least ten days after the date on which the election is received. Additional shares of common stock acquired under the Plan will be purchased in the open market, on the NYSE or otherwise, at prices that may be higher or lower than the net asset value per share of the common stock at the time of the purchase. The number of shares of common stock purchased with each dividend will be equal to the result obtained by dividing the amount of the dividend payable to a particular shareholder by the average price per share (including applicable brokerage commissions) that the transfer agent was able to obtain in the open market. The Fund will not issue any new shares of common stock in connection with the Plan. There currently is no charge to participants for reinvesting dividends or other distributions. The transfer agent's fees for handling the reinvestment of distributions will be paid by the Fund. However, each participant pays a pro rata share of brokerage commissions incurred with respect to the transfer agent's open market purchases of common stock in connection with the reinvestment of distributions. The automatic reinvestment of dividends and other distributions in shares of common stock does not relieve participants of any income tax that may be payable on such distributions. -------------------------------------------------------------------------------- UBS Global Asset Management 27 Insured Municipal Income Fund Inc. GENERAL INFORMATION (UNAUDITED) DIVIDEND REINVESTMENT PLAN (CONCLUDED) Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund reserves the right to amend or terminate the Plan with respect to any dividend or other distribution if notice of the change is sent to Plan participants at least 30 days before the record date for such distribution. The Plan also may be amended or terminated by the transfer agent by at least 30 days' written notice to all Plan participants. Additional information regarding the Plan may be obtained from, and all correspondence concerning the Plan should be directed to, the transfer agent at PFPC Inc., P.O. Box 43027, Providence, Rhode Island 02940-3027. For further information regarding the Plan, you may also contact the transfer agent directly at 1-800-331-1710. -------------------------------------------------------------------------------- 28 UBS Global Asset Management Insured Municipal Income Fund Inc.
